G91 option of F as in the pendent source code

[charroch]

Hello,

I am trying to build something similar to the pendant with source code here:

https://github.com/Duet3D/CNC-Pendant-Firmware/blob/master/src/CNC-pendant.ino

The code uses G91 to move relative to current position with the extra value of F6000 (or F600 for Z). What does the F command option do?

Thanks,
Carl

@charroch Feed rate as per G0...

@charroch G91 doesn't accept any parameters. it switches to relative mode https://duet3d.dozuki.com/Wiki/G91
F6000 for example is typically added to G0, G1 etc to set the movement speed
